Procedure

To a solution of 7-(4-chlorobenzyl)-1-(4-methoxybenzyl)-3-methyl-8-(3-(3-(trifluoromethoxy)phenoxy)propyl)-1H-purine-2,6(3H,7H)-dione (105 mg, 0.167 mmol) in DCM (4 mL) was added TFA (1 mL) dropwise followed by trifluoromethanesulfonic acid (0.25 mL) at 0° C. The reaction was stirred at 0° C. for 10 min, then at room temperature for 16 h. The reaction was quenched with saturated sodium bicarbonate and extracted with DCM. The organic phase was washed with water, dried over sodium sulfate, and concentrated to give 7-(4-chlorobenzyl)-3-methyl-8-(3-(3-(trifluoromethoxy)phenoxy)propyl)-1H-purine-2,6(3H,7H)-dione (66 mg, 77.6% yield) as a yellow oil. LCMS retention time 2.868 min; LCMS MH+ 509.
